What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Phase Linear Model 2000

The Model 2000
Stereo pre-amplifier offers excellent specifications, outstanding sonic
performance and a unique "Ambience Circuit" designed to retrieve
out-of-phase signals while using the 2000 in a stereo mode. Prior to this time
one had to add another amplifier and an additional set of speakers to utilize
such a system, but this is not true of the ambience system in the 2000. When
listening to a record played through the 2000 with the ambience circuit on, you
will hear instruments that would not be audible on our preamps. The music is on
the record out of phase and the 2000 corrects that problem

"In
measurements made at CBS, the Model 2000 proved itself a strong performer. In
neither channel did output clipping occur at less than 12,2 volts, whether
driven singly or together. At an output level of 2 volts (more than enough for
full output from most power amps), harmonic distortion was less than 0,02% in
all cases - well below Phase Linear's 0,1% spec. And if we ignore as inaudible
all harmonics above 20 kHz, harmonic distortion is no more than 0,0066%"

"The Model 2000
is as super in the listening as it is smooth in the handling. Once one has
become used to the controls, they are convenient to operate and satisfying to
touch. The extra flexibility in the tone controls (the separate knobs for each
channel, as well as the variable turnover points) delivers worthwhile
options."
